  • Patent number: 4455618
    Abstract: A programmable calculator employs modular read-write and read-only memories separately expandable to provide additional program and data storage functions within the calculator oriented toward the environment of the user and two sixteen bit LSI NMOS central processing units. One of the central processing units (LPU) is employed to perform language syntaxing, arithmetic, and general supervision of program execution. The second central processing unit (PPU) is employed for managing input/output operations. Communication between the two central processing units is accomplished by an arrangement through which the two central processing units share a common portion of memory. The calculator also includes a keyboard having a full complement of alphanumeric keys for entering programs and data into the calculator and for otherwise allowing the user to control operation of the calculator.

  • Patent number: 4300790
    Abstract: As a separable part of a multiple set of carbon interleaved forms for use with a computer terminal, the invention comprises a separable flap having a free lower edge and hingedly secured adjacent its upper edge to the upper end portion of the set with precisely located input area designations imprinted on its under surface for display in accurate relationship to the set forms when the free edge is lifted and swung upwardly through an arc of 180 degrees for insertion into the terminal, whereby following entry of the desired input area data on the flap, the latter may be separated from the set and discarded without wasting the hyperextended portions of a prior art set that have been required when the input area was disposed on the upper portion of the usual cover sheet.
